Cee Lo Accuser Claims He Sexually Assaulted Her in Sushi Joint

As we first reported, the LAPD has launched an investigation into the woman's allegations. Sources tell us, detectives went to the restaurant last week and interviewed several employees, including the manager, to determine if anyone saw the alleged attack.

We're told the accuser is NOT an employee of the restaurant ... she's someone Cee Lo brought to dinner.

Cee Lo tells us the woman's claims are BS and that he hasn't been to the restaurant for 3 months.

Our sources say, the accuser told cops the alleged incident occurred several months ago. It's unclear why she waited so long to file a police report.
